Let x = the time (in 10−1 weeks) from shipment of a defective product until the customer returns the product. suppose that the minimum return time is γ = 3.5 and that the excess x − 3.5 over the minimum has a weibull distribution with parameters α = 2 and β = 2.5.(a) what is the cdf of x? f(x) = 0 x < 3.51−e^−((x−3.5)2.5)2 x ≥ 3.5(b) what are the expected return time and variance of return time? [hint: first obtaine(x − 3.5)andv(x − 3.5).](round your answers to three decimal places.)e(x) = 10^−1 weeksv(x) = (10^−1 weeks)2(c) computep(x > your answer to four decimal places.)

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
